CONTROL DEVICE AND CONTROL METHOD FOR VARIABLE VALVE TIMING MECHANISM

摘要

The present invention relates to a control device of a variable valve timing device and a control method for a variable valve timing device. an electronic control device with a microcomputer adjusting valve timing to a target change rate according to a deviation of the target change rate and output of a sensor detecting a change rate of the valve timing caused by the variable valve timing device. The present invention includes the sensor detecting the change rate of the valve timing caused by the variable valve timing device and the electronic control device with the microcomputer.
